Transalpin
The Transalpin is an EuroCity express train linking Zürich (Switzerland) with Graz (Austria) via Liechtenstein. Introduced in 2013, it is operated by the Austrian Federal Railways (ÖBB) and the Swiss Federal Railways (SBB-CFF-FFS). From 1958 to 2010 a train of the same name linked Basel or Zürich with Vienna (see history below).
The name of the train alludes to the fact that it crosses the Alps. Transalpin was also the Ancient Roman word meaning "behind the Alps", and referring to the region of that name in northern Switzerland.
